Mice are not only unpleasant, but they also pose great risk to the people within a home. The biggest threat they pose are the different diseases they carry. Salmonella, hantavirus, and lymphocytic choriomeningitis (LCMV) are just a few of the most common diseases mice carry and can transmit to humans. Mice spread these diseases through their droppings and their urine, which they often use to mark their territory.
The damage mice cause can also harm the people within a home. As they chew through packages of food and other items, they also contaminate them, making it very dangerous for anyone who touches the same surface or consumes the food. Mice will also chew through wiring in a home, which can cause a house fire. If a mouse chews through a gas line, it could also expose the occupants in a home to carbon monoxide poisoning.
